Quality checks for quality specs

Looking great in your new glasses is one thing, but we also want you to be confident in knowing you’re rocking some quality eyewear.  So, before your order is dispatched, we take some time to check your glasses are completed to the best possible standard.

All prescription glasses are taken through the following quality checks…


 1). Your Prescription

We check the prescription is correct to the values that have been provided by you. This means checking the sphere and cylinder powers and the axis. Your finished glasses are then checked on a focimeter for an accurate reading.


 2). Pupillary Distance (PD) and Heights

We check the PD values on your glasses are correct to your given measurements. We also check the vertical alignment of the lenses to ensure an optimal position when the glasses sit on your face.

 3). Lens Thickness

We check that the lenses in your glasses are the correct index and are as thin as possible based on a combination of factors including your prescription and choice of frame.

 4). Front Curvature

Most prescription frames in our collection have a subtle curve to them.  We therefore check that the lenses in your glasses have the correct curvature, so they fit the frame correctly and are not likely to fall out or damage the frame.


 5). Fitting Bevel & Groove

To ensure the lenses are fitting securely in the frame, we check that the fitting bevel and groove on the lens is sufficient for each frame.


 6). Lens Safety

We check that a lens does not have any sharp edges. This is particularly important for semi-rimless or rimless glasses where the lens edges are exposed.


 7). Lens Surface Quality & Anti-Reflection Coating

We check that the lens surface is free from any marks or scratches that may have occurred during the manufacturing process, as well as ensuring the anti-reflection coating is uniform across the surface. If this is not correct the coatings can break down over time meaning the lenses would need to be replaced.


 8). Frame Alignment

We don’t want you looking wonky, so we check that the frame is correctly set up and the arms are not out of alignment. On occasion frames can be slightly misaligned due to the installation of prescription lenses, but this is rectified before being packaged and shipped.


 9). Nose Pad Alignment

If your frame has nose pads, we check they are securely attached and positioned. If the positioning is not right for you, they can be gently adjusted to suit.


 10). Temple Tip Adjustment

We check that the ends of the arms are correctly positioned. As above, the temple tips can be gently adjusted to suit you.


 11). Overall Lens Shape & Symmetry

We check the lenses are the correct shape for the frame and are both symmetrical.


 12). Lens Fitting

We check all lenses fit snug in the frame, too loose and they will rattle in the frame or worse, fall out. If they're too tight they can distort the frame.


✓ 13). Treatments & Coatings

We check that any treatments and coatings have been applied correctly.


 14). Overall Cosmetic Appearance

To be super sure you’ll be donning that quality pair of glasses, that’s pleasing to the eye, we have one final check of your glasses and make any final adjustments.


Quality matters…

We take great pride in ensuring you are looking and feeling great in your eyewear, so if your glasses do not pass our strict quality checks, we will remake your glasses.

In the unfortunate event that this happens, we will inform you by email or phone.
